No.
The 721 was the original 12 port head on the 12 port 100/6.
The 960 casting was subsequently used on most later 3000 engines -  
don't know the exact changeover.
So no 960 is not peculiar to the BJ8. At one point I thought it was,  
but it isn't.
There was also some weird 'smog'/ air head but I haven't ever seen it,  
don't know the casting number.
The 'majority' of c series 12 port heads are 721 (100/6) or 960 (3000).
